使用脉冲响应不变法实现巴特沃兹低通滤波器(Butterworth low-pass filter impulse response invariance)

matlab编程通过MUSIC算法定位声源方向（DOA），图形最高点对应横坐标即为声源方向(MUSIC algorithm matlab programming by positioning the sound source direction (DOA), the horizontal axis corresponds to the highest point of the graphic is the sound source direction)

DataBurn is an Objective-C example which demonstrates some of the features of DRTracks. The sample illustrates how to create a DRFolder from an existing folder on the source disk and burn it to disc, creating a hybrid ISO9660/Joliet/HFS+ data CD. The sample also uses the DiscRecordingUI framework to present the standard burn setup and progress user interfaces.

YBUS FORMATION IN POWER SYSTEM

This function SNAKE implements the basic snake segmentation. A snake is an active (moving) contour, in which the points are attracted by edges and other boundaries. To keep the contour smooth, an membrame and thin plate energy is used as regularization.

计算灰色关联度，可用于多指标的多方案评价，关联度大的为优，小的为劣。(Gray correlation calculations can be used for multi-index multi-program evaluation, excellent correlation for large and small for the poor.)

a new circuit topology of a phase-locked loop that can be used for synchronising a singlephase wind turbine generator (WTG) with the low voltage utility grid. The circuit is based on the time-delay digital tanlock loop (TDTL) architecture and was modelled and simulated using Simulink/MATLAB. The results presented demonstrate the ability of the circuit not only to synchronise a WTG with the grid, but also to re-gain synchronization following a sudden disturbance in the grid voltage. The simulated disturbances included a ramp and a multi-step change in the phase of the grid voltage waveform.
